IV'ENCIL CALENDAR.

Application filed February 2, 1924. Serial No. 620,271.

To all whom it may concern: I

Be it known that LYALMA H. Roenns, a citizen of the United. States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Pencil Calendars, of which the following is a speci-' fication.

This, invention relates to a pencil calen dar and iinportant objects thereof are to provide a perpetual calendar which is simple in its construction and arrangement, strong, light, durable and efficient in its use, attractive in appearance and comparatively inexpensive to manufacture.

"lVith the foregoing and other objects in view which will appear as the description proceeds,'the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereinafter disclosed can be made within the scope of the claim hereunto appended without departing from the principle of the invention.

In the drawing forming a portion of this specification and wherein like numerals of reference designate corresponding parts throughout the several views Figure 1 is a vertical side View of a pencil calendar in accordance with my invention.

Figure 2 is a similar View with parts thereof shown in cross section.

Figures 3 and l are plan views of the calendar sleeves.

Referring in detail to the drawing 1 denotes a tubular sleeve like member of subing the member 1 in the mounted position.

The inner wall of the groove 2 is marked with the names of the months of the year,

indicated at 5, which extend longitudinally of the member 1 A pair of sleeves 6 and 10 are revolubly mounted in the groove 2 of the member 1. The sleeve 6 is of a greater length than the sleeve 10 and is positioned below the latter; The sleeves 6 and 10 frictionally engage the inner wall of the groove 2 to retard their rotary movement thereon except when manually shifted for the purpose of adjustment. Such adjustment is facilitated by providing the sleeves G and 10 with circumferentially extending knurled ribs 11 and '12, respectively, the former being disposed at the lower end of thesleeve 6 and thelatter at the upper end of the sleeve 10. By this arrangement an uninterrupted surface is provided by the sleeves 6 and 10 be-,

tween respective lmurled ribs 11 and 12. The ribbed end of the sleeve 6 rides against the lower side wall of the groove 2. The ribbed end of the sleeve 10 rides against the upper-.side wall of the groove 2. The said side walls are flaring to prevent any binding action between the walls of the groove and the ribbed ends of the sleeves.

The surface of the sleeve 6 is marked with numerals 7, indicating the days of the month. The numerals 7 run from 1 to 31 corresponding with the days of the longest months, and are arranged in seven longitudinal columns or in superposed circles of numerals with seven numerals in each circle, thefirst circle including the numerals from 1 to 7, the second from 8 to 14, etc., the last circle containing onlythe numerals 29 30 and 31. The sleeve 6 is further formed with a lengthwise extending elongated slot 8 disposed intermediate an adjacent pair of longitudinal columns of numerals 7. The slot 8 is adapted to register with any one of the names 5' of the months, formed on the inner wall of the groove 2, of the member 1, when the sleeve 6 is adjusted upon the latter in the manner above described. I

The surface of the sleeve 10 is marked with abbreviations 9 of the days of the week, namely, Sun for Sunday, Mon for Monday, etc. Each of the abbreviations 9 is disposed to extend longitudinally, and is respectively aligned with the vertical columns of numerals 7 formed on the other sleeve 6.

In practice my improved perpetual pencil calendar is adjusted as follows The names of the months, as indicated at 5, being formed on the inner wall of the groove 2, of the member 1, the sleeve 6, is revolved thereon until the slot 8, in the cylinder 6, is brought to register with the month desired. By now shifting the sleeve 10, the abbreviations 9 of the days of the week, may be aligned to respectively correspond with the proper longitudinal columns of numerals 7 to provide a correct calendar for any desired month of the year.

It will, of course, be obvious that adjustment of my improved calendar will be required only on the first day of each month.

From the foregoing description taken in connection with the accompanying drawing, the principle of eonstructionand the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while describing what is now thought to be the best embodiment thereof it is to be understood that the device shown in the drawing is merely illustrative and that various changes in the form, proportions, and minor details of construction may be resorted to without departing from the principle, or sacrificing any advantages of the invention, which come within the sco e of the claim hereunto appended.

l1at I claim is: A device for the purpose set forth comprising a tubular sleeve like member formed intermediate its ends with a wide circumferentially extending continuous groove having means on its inner wall to indicate the months of the year, a pair of opposed revoluble sleeves mounted in said groove and one abutting against one side Wall and the other against the other side wall of said groove, one of said sleeves having means on its periphery to indicate the days of the month and the other with means to indicate the days of the week, and that sleeve having the days of the month indications formed with a lengthwise slot to selectively expose a month indication, said slotted sleeve of greater length than the other sleeve and having said slot ends.

In testimony whereof I affix my signature.
